To ask how much sleep you get?

[Purplerain101]

On average how much sleep do you get every night? And how much sleep do you actually need to feel refreshed?
I probably get about 6 hours per night, but ideally need about 8 hours to feel bright eyed (never get that much though).

I work 3 nights a week and have an hours sleep before a shift and two hours after a shift. The other 4 nights I sleep from 11pm to 8.30 am.
